दी गई श्रृंखला में प्रश्न – चिह्न (?) के स्थान पर क्या आएगा?
15, 22, 36, 57, 85, ?
Detailed Solution & Logic
Correct Answer:
120
Series:
15, 22, 36, 57, 85, ?
पहले अंतर (differences) निकालते हैं:
22 − 15 = 7
36 − 22 = 14
57 − 36 = 21
85 − 57 = 28
अब अंतर की श्रृंखला है:
7, 14, 21, 28
यह हर बार 7 से बढ़ रही है।
अगला अंतर = 35
अब अगला पद:
85 + 35 = 120
Correct Answer: 120
